This analogy fails because there are tasks that can be done by two persons and
not by one alone.
This is not the case for CPUs.

The only difference I can think of is, that two CPUs can compute two result
simultaneously!
I think this is where you need to look for your holy gral ;)
Find an algorithm where "causality" is important - sounds like something the
quantum computer can take advantage of and not regular computers.

Any other senario, and it won't matter if one operation is done before or after
the other, in which case it's possible to task switch between the two threads.
(of cause you wouldn't need 2 threads, might be easier to rewrite the algo. as a
pure serial one).
